Sarah VanSlette: Cycling Instructor

“Character cannot be developed in ease and quiet. Only through experience of trial and suffering can the soul be strengthened, ambition inspired, and success achieved.” -Helen Keller

Sarah was first certified as a spinning instructor when she was just a college student, and now she teaches college students as a professor at SIUE. Through graduate school she taught spinning at two Big Ten Universities (Purdue University and Michigan State) before moving back to St. Louis where she taught in Chesterfield. While she never stopped spinning (she was happily spinning the week before her first child was born!), she did take a break from spinning instruction, but is excited to be back in the saddle. Sarah is passionate about spinning because it can provide an intense workout to people who may not be able to run or perform high impact exercises.

Max Anderson: Cycling Instructor

“It’s never too late to become what you might have been.”  –George Eliot

Basically I feel like that person who woke up one day and said “I’m going to make a positive, challenging life change for myself and make it work.”  I was at a point where I was feeling very directionless and began noticing years of fatigue catching up with me, so I decided that I needed a fresh start and to work towards something different from anything I had pursued in most of my life.  I started exercising every day I possibly could and began eating healthier with the goal in mind of one day being a personal trainer/fitness instructor.  “Being a fitness instructor means not only getting to change myself for the better, but to positively affect other peoples’ lives on a personal level as well.”

Max loves spinning to different genres of rock music and creating interesting themes that you will remember.

Vona Kuczynska: Cycling Instructor

“If life gives you lemons, make lemonade… Then find someone whose life has given them tequila, and have a party!”

Growing up, I practiced martial arts and participated in track and field, rowing, and cycling. I enjoyed organized sports because I’m social, enjoy pushing myself, and competing. These days, I mostly compete against calories from beer, French fries, and chocolate. They are a tough adversary!

I started spinning to combat the enemy, listen to good tunes while working out, and meet interesting people – all at the same time! As a wildlife biologist, I spend most of the summer in the woods, climbing trees, catching and tracking birds and bats, often up and down mountains while carrying a 40-pound backpack. It helps to stay in shape the rest of the year and keep my legs and core strong so that come summertime, my only worries are mosquitoes and the heat!

In my spare time, I enjoy all the typical granola activities: hiking with my dogs, riding my bike, backpacking, camping, canoe/kayaking, climbing, microbreweries, and traveling to remote natural places.

Favorite spin music: Anything upbeat with a fast tempo that I can wiggle around to such as Bloodhound Gang– The Bad Touch or Outkast– Hey Ya!

Stephanie Morris: Cycling Instructor

“Being challenged in life is inevitable. Being defeated is optional.”

Stephanie has always been an active person but developed a real interest in the full scope of health and wellness some years ago. She was set on course to become a fitness instructor herself when she became close friends with a class at a local gym. Her “fit-fam” of friends from the class pushed her out of her comfort zone and encouraged her to become an instructor. Stephanie’s Cycle class aims to keep you encouraged, motivated, and inspired while incorporating sprints, jumps, hills, and climbs into playlists of various genres. Her low-impact and high energy PiYo class, utilizing dynamic and powerful flows, is a great complement to more high-impact workouts. Stephanie’s goal with every class is to help you challenge yourself on your fitness journey and have fun along the way!
